Since we changed the nowplaying panel in v3.83 to allow filters you will temporarily need to specify the text color by adding the following to the nowplaying.dis.

a:link { color:#000000;}
a:visited { color:#000000;}

Set both to the same #color you want the artist, title, and album text to be.

We have fixed this in v3.85 so that the color values specified in the .songtitle .artisttitle and .albumtitle get applied to the text properly so that the above will not be necessary.
